In long ago times, voodoo doctors thought it best to avoid any type of interaction with blood. They knew that the life of a person is in their blood, and any interruption of blood flow could shorten their life span. They knew also that when you have personal interaction with someone else's blood, you establish a claim against your life span.
Today, surgery is recommended for virtually every major medical event. If we were to follow the advice of voodoo doctors, we would shut down every major medical center, except for emergency rooms. We also would bar anyone from performing surgery of any kind.
